Frequently Asked Questions
Can 78L05 replace LP2950Z?
No, the 78L05 cannot directly replace the LP2950Z. The 78L05 is a linear voltage regulator, while the LP2950Z is a low-dropout (LDO) voltage regulator. LDO regulators have several advantages over linear regulators, including lower dropout voltage, lower quiescent current, and better transient response. If you need to replace an LP2950Z, you should use another LDO regulator with similar specifications. Some possible replacements include the LM2940Z, LT1963, and TPS7A4700.
How to use SG3525?
To use the SG3525, you will need to connect the following components: Input voltage Output voltage Feedback resistor Timing resistors and capacitors MOSFETs Inductor Transformer (if necessary) , and refer to SG3525 datasheet pdf
